1996 Chevy Camaro stumbling on acceleration

My car runs pretty good on cruise but stumbles very badly on acceleration. Either from a stop or cruising on any road. Ihave replaced all plugs at least 3 times the spark wires 2 or 3 times with some individual wires being replaced too seperately. Used(new to me) coils indiviually or complete coil pack. New TPS, new(to me ) MAFS. I found and fixed 2 vacuum hoses, It has improved slightly with all this but still is a pain to drive. Forget stomping it to pass someone. I truly would like to provide a donation but I'm so broke I can't even pay attention. Any help would be appreciated. Thank You
